To all whom it mcyconcern: a

, Be it known that l, Riot-man PALMER, a subyect ot the King of England,residing at South Alburg, in the county oi? Grand isle and State ofVermont, have mvented cerliELlIl new and useful Improvements in r atlllGSf and (l ClGClEtTG the fOllO Wlll b0 b6 afull, clear, and exactdescription of the invention, such aswill enable others skilled in theart to which it appertains to make and i use the same.

This invention relates to an improved rail tie, and it has for itsprmclpal ob ect to generally improve upon devices oftlus class byproviding oneott extreme simplicity and durability which comprises aconnecting bar or tie provided on ltS under face and near its oppositeends and directly beneath the rails with a yieldable cushioning meanswhich serves to relieve the rails from violent shocks and jars to whichthey are subjected,

thereby decidedly increasing their lite.

More specifically speaking, itis another object of the invention toprovide a tie which dill till

' is termed at its opposite ends with pockets in which aresilientsiibstanceis placed, the tie proper resting directly on thissubstance which is intended to yield sufliciently to absorb the shocksto which the rails are subj ected when a train otcars is passing there-Iover.

Uther objects and advantages of the in vention will be apparent duringthe course of the following description;

llin the accompanying drawings forming a part of this specification andin, which like numerals are employed to designate like parts throughoutthe same;

Figure 1 is a central longitudinal. sectional view through a rail tieconstructed in accord-- ance with this invention, and showing the samein use.

Figure 2 is a side elevation view thereot Figure 3 is a bottom plan viewof one of the cushioning members. p i

lFignre 4; is a transverse vertical section taken onthe line die-d ofFigure 1.

ltn the drawing,the reference character 1 designates a cross-tie, acrosswhich the rails means for co-operation with the underface oi the t1eadjacent the opposite ends thereof for absorbing shocks andjars to whichthe rails are subjected. Although the means could be of some otherconstruction, it com prises whatmay be conveniently termed, a pair ofpockets formed at the opposite ends by a pair oi? substantially il-shaped resilient metal straps 2 which have their opposite ends bent toextend in parallelism with the tie and formed with slots 3 slidablyengaged with bolts at extending vertically through the tie. With thisarrangement, the ends of the straps are permitted to move in a manner topermit the filler 5 in the pocket to become etl'ective in absorbing theshocks.

Although the filler could be of any other substance or material, it ispreferably composed of evaporated tar mixed with sand and saw-dust torender it sufliciently rigid to serve for effectively accomplishing theends sought. The tie directly bears on the filler so that the shocks aredirectly taken up by the latter. By preference, short anchoring blocks 6are embedded in the tar and these are formed with sockets into which thelower ends of the aforesaid screws are received to hold the latteragainst misplacement, For the purpose of confining the filler in thepocket, I preterto use side plates 7, these being connected with thevertical sides of the tie in a manner to permit relative movement of thelatter with respect to the plates. As shown, the plates are formed tractthe filling material and render it more rigid.

From the foregoing description it is clearly apparent that when therails are subjected to shocks by a passing train, the filling material 5will serve as a shock absorbing medium and due to the fact that the endsof the plates 2, which form the pockets have slidable connection attheir ends with the tie, they will compensate for the downward movementof the latter. This novement will not be interfered with by the plates 7as these have a slidable connection with the tie so as to permitrelative movement of the same with respect to the confining plate. Idesire to point out that the filling material in practice must be suchas to prevent it from freezing in cold weatheror melting in extremelywarm weather, and although I have specified a certain kind of materialfor use, I Wish it to be understood that any other kind of suitablematerial may be employed. As a matter of fact, a wooden block maysuffice as a substitute for the resilient filling material It is ofcourse'understood that when a tie is in use, the pockets, sideplates andthe filling material will be embodied in the ground to anchor the tieand prevent slippage thereof.

By carefully considering the foregoing description, in connection withthe drawings, persons familiar with devices of this class Wllldoubtlessbe able to obtain a. clear umlerstanding oi? the invention.

Therefore, a more detailed description is deemed unnecessary.

Since probably the best results may be obtamed With the construction andarrangewment herein shown anddescribed, this is taken as thepreferredembodiment of the invention. However I wish it understood thatminor changes coming within the scope of the inventions as claimed maybe resorted to if desired.

I claim 1. In combination a rail tie, strips of resilient materialconnected at their outer ends to the under-face of the tie near theopposite ends of the latter, said strips forming pock ets, a quantity ofyieldable material arranged in said pockets, the tie resting directly onsaid material.

A rail tie cushioning means comprising a substantially U-shapcdresilient metal trap designed to have its opposite ends slidablyconnected vith the under side of the tie, said strap serving to term apocket. :1 quantity of yieldable material designed to be placed in saidpocket, and means embedded in said material to permit connection offastening screws for the ties therewith.

3. The structure set forth in claim :2, together with a pair of sideplates for conlining the material in said pockets said side plates beingdesi ned to have slid able connection with the tie so as to permitrelative movement of the latter with respect therelo.

l. In combination, a rail tie a pair of substantially U-shaped resilientstrips of metal having their free ends contacting the underside o'f-saidtie and formed with slots fastening means passing through the tie, saidslots slidably engaging with such laslenings, said stripsformingpockets, resilie.1t liliing material arranged in said pockets,blocks embedded in said material with which the lower end of the railfastening bolts are connected, side plates for confining the material insaid pockets. said side plates being formed at the upper edge withvertical slots, and bolts passura through said slots and connected withthe tie to permit relative movement oi" the latter with respect to saidside plates.

In testimony whereof I have hereunto set my hand.

RICHARD PALMER.
